| 词条 | Rutford Ice Stream |
| 释义 |
The ice stream is situated in a deep trough which is a tectonic feature between the Ellsworth Mountains and the Fletcher Promontory. Because of this the ice stream position may have been stable for millions of years. The bed of the ice stream reaches {{convert|2000|m|ft}} below sea level. Therefore, between the bed of the ice stream and the height of the Ellsworth Mountains there is a vertical relief of {{convert|7|km|mi}} over a distance of only {{convert|40|km|mi}}.[2] At the upper (inland) end of the ice stream the ice thickness reaches {{convert|3100|m|ft}} falling to around {{convert|2300|m|ft}} in the trough. Flow speed reaches a maximum of around {{convert|400|m|ft}} per year about {{convert|40|km|mi}} inland from where the ice stream meets the Ronne Ice Shelf and starts to float on the sea.[2] The speed of the Rutford ice stream varies by as much as 20% every two weeks, in response to variations in the tides.[3] Tributary glaciers
